METAL FILING.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed December 14, 1910. Serial No. 597,344.

To all whom it may concern:

Be it known that I, ERNEST ALBERT GAR- RA'IFT, of 78 Gracechurch street, London, England, consulting engineer, have invented certain new and useful Improvements in Metal Piling, of which the following is a specification.

This invention relates to metal sheet piling, and in particular to interlocking members of the clutch type, that is to say in which the interlocking member has clawlike flanges bent over more or less parallel to the transverse axis of the member, (2'. e. the axis transverse to the run of the piling) so as to embrace the flange or flanges of I bars, channels, or bars of other section forming the piling, to act as guides for the same in driving and to form therewith when driven the wall of the piling.

In the specification of a previous application for patent S. No. 574,606 filed 30 July 1910 I have described forms of riveted interlocking member of this character, whereby a number of advantages can be secured, for example the pile-engaging elements of such interlocking members can be produced without necessity for special bending operations for turning the hooked edges, the elements can be riveted together without necessity for countersinking and without obstructing the guiding of the piling in the interlocking member during driving.

The present invention has for its object to provide a new or improved riveted interlocking member whereby similar advantages may be secured.

According to this invention the interlocking member is constructed of two rolled iron or steel sections. Each of said sections has a mid-web provided on each side with a shoulder and with a pile-engaging flange or extension adapted to receive and guide the pile. The two elements are placed with their mid-webs in alinement and cover plates or bars are applied on each side of the mid webs and the whole is secured firmly together to form a strong structure by means of rivets passed through the cover plates and mid-webs of the elements. The shoulders before mentioned project on each side and so provide a recess of sufficient depth that the rivet heads without countersinking may be flush with or behind them. At the same time the shoulders form an abutment on each side of the clutch and cooperate with the pile engaging flanges thereof to guide the flanges or transverse faces of the piling bars.

For interlocking piling bars of I-section, the pile-engaging edges of the interlocking member will be of hooked section. For interlocking piling bars of channel or like section, the interlocking member may have two hooked edges for engaging the flange of a channel bar at each side, and two outwardly flanged edges for receiving and seating the back corners of such channel bars at each side. The piling engaging flanges or portions of the interlocking member may be otherwise varied within certain limits in accordance with the shape of the piling bars to be engaged and interlocked.

The accompanying drawings show by way of example four forms of interlocking member according to the invention.

Figure 1 is a cross section of one form of the interlocking member applied to I-bar sheet piles. Fig. 2 is a side elevation thereof; Fig. 3 is a cross section of another form of the interlocking member applied to channel bar sheet piles and Fig. 4 is a corresponding elevation. Fig. 5 is a cross section of another form of interlocking member. Fig. 6 is a similar View to Fig. 3, and shows another modification.

In Fig. 1 the interlocking member consists of two bars or sections A each rolled with a mid web portion a projecting shoulders or joggles b and hooked edges 0 these two bars or sections being placed with the mid-web port-ions in alinement and riveted up between cover plates or bars (Z. It will be seen that the shoulders 6 project on each face of the mid-web and provide a recess c in which the heads of the rivets f can lie without presenting any obstruction to the driving of the piling bars g, the flanges of which are engaged and guided by hooked edges 0 and shoulders I).

The form of interlocking member shown in Figs. 3 and 4 is similar to that of Figs. 1 and 2 except that two flanges or edges of the pair of pile engaging elements B are of hooked section 0 to engage the flanges of channel piling bars 7L disposed facing in opposite directions alternately, while the other two edges of the pile engaging elements are formed as outward flanges 27 to receive and seat the back corners of the channel bars.

In cases where it is desired to have the channel bar piles facing in one direction instead of in alternate directions, the interlocking member may have two hooked flanges at one extremity to engage a chan nel bar flange at each side, and two straight flanges at the other extremity to receive the back corners of the channel bars at each side. Such a modification is shown in Fig. 6, similar letters indicating corresponding parts.

The elements of the interlocking member are shown as rolled with a groove or channel j for lightness and economy, but the elements might be rolled of full section of this part. The mid web portion a may with advantage be tapered slightly as shown and the cover plates be formed with -a corresponding bevel. The spaces 6 may be filled with a packing or grouting of sand, cement,

concrete or the like if desired. The elements of the interlocking members can be produced by ordinary rolling operations and without necessity for special bending operations for turning the edges. Also the depth of the interlocking member 6. its transverse width) can be increased or diminished within certain limits and without destroying the symmetry of the interlocking member by altering the transverse distance apart of the rivets. I

In some cases I may rivet the mid web portions of the clutch elements together face to face instead of in alinenient and I may then dispense with the use of cover plates. Or instead of employing two cover plates with alined mid web portions I might employ only one cover plate. Fig. 5 shows a clutch member in which the mid web portions a of the elements are riveted together face to face. The clutch elements are shown as formed'with hooked edges for engaging with piling bars of I section, but they may be formed to engage piling bars of channel or other section.

lVhat I claim and desire to secure by Letters Patent is 1. An interlock clutch for metal piling, comprising in combination two bars, each rolled with a mid-web portion and on each side thereof with a shoulder and with a pileengaging flange overhanging said shoulder, said bars being secured together by rivets, and the four shoulders of the two bars being adapted to cooperate with the pile engaging flanges to guide the piling bars and forming at each side of the clutch a recess adapted to accommodate the rivet heads, substantially as described.

2. An interlock clutch for metal piling, comprising in combination two bars each rolled with a mid-web portion and on each side thereof with a shoulder and with a pile engaging flange overhanging said shoulder,

said bars being located with their mid-web portions in alinement, and a cover a plate riveted to said alined mid-web portions, the four shoulders of the two bars being adapted to cooperate with the pile engaging flanges to guide the piling bars and forming at each side of the clutch a recess adapted to accommodate the rivet heads, substantially as described.

3. An interlock clutch for sheet metal piling, comprising in combination two bars each rolled with a mid-web portion and on each side thereof with a shoulder and with a pile engaging flange overhanging said shoulder, said bars being located with their mid-web portions in alinement, cover plates at the sides of said mid-web portions and between which they are riveted, the four shoulders of the two bars being adapted to cooperate with the pile engaging flanges to guide the piling bars and forming at each side of the clutch a recess adapted to accommodate the rivet heads, substantially as described.

4. An interlock clutch for sheet metal piling, comprising in combination two bars.

each rolled with a mid-web portion and on each side thereof with a shoulder and with a hooked flange overhanging said shoulder and adapted to receive the flange of a pile, said bars being secured together by rivets, and the four shoulders of the two bars being adapted to cooperate with said overhanging hooked flanges to guide the piling bars and forming at each side of the clutch a recess adapted to accommodate the rivet heads,

substantially as described.

5. An interlock clutch for metal piling, comprising in combination two bars, each rolled with a mid-web portion, and on each side thereof with a shoulder and with a hooked flange overhanging said shoulder and adapted to receive the flange of a pile,
